PIE template
Fragment of a discussion from User talk:Rua
I wouldn't know what the requirements of those families would be. For starters, these languages probably don't have modifiable or affixable roots in the sense of PIE. In the Uralic family, for example, there is such a thing as a "root" but it's always also a noun, adjective or verb. Someone who is more familiar with them should probably do it instead.
